The invention relates to threshing machinery and particularly to an interchangeable straw bruiser and wind stacker.

Threshing machines as now standard in the art are provided at their rear ends with an open ended, inclined straw delivery or discharge chute. The usual way of disposing of thestraw is to connect a wind stacker to the open end of this chute, which stacker receives the straw from the chute and pneumatically discharges the same out of the machine. Sometimes it is desired to break up the straw into shorter lengths before discharging the same. Accordingly, so called straw bruisers are provided, which break up the straw by a bruising or chopping action.

The objects of this invention are to provide a wind stacker for threshing machines, which may be easily and quickly converted into a straw bruiser without the aid of any special tools or the expenditure of any great physical effort, and to provide such structure cheap to produce and which will readily adapt itself for use in connection with standard threshers without materially altering their construction. i

Briefly, these desirable objects are ,accomplished by providing on the wall, which surrounds the opening in the straw chute,

or bruiser carrier plates. The usual fan hous ing and cover is provided with a shaft which is designed to carry either a conventional wind stacker fan or a plate provided on one face with fan elements and on its other face with bruising elements, a distributor element, and auxiliary fan elements.

Looking now to the drawings, wherein a I practicable embodiment of this invention has been illustrated by way of example,-

Figure 1 is a side view of the rear end of a threshing machine showing the stacker attachment; 7 V Figure 2 is a fragmentary, rear elevation of the structure shown in Figure 1 with the lower half through the straw chute and fan housing appearing in section;

Figure 3 is a perspective view with the cover swung open to show the arrangement when 5 it functions as an ordinary wind stacker; and;

means removably to carry either blank plates Figure 4: is a similar perspective View showing the arrangement when it is to be used for bruisingthe straw.

A conventional thresher has been shown, having a body 10 provided at its rear end with the usual downwardly and outwardly inclined straw delivery or discharge chute 11 open as at 12. Surrounding this opening is a vertical wall 13. This wall carries in a manner to surround the opening 12 two spaced channel-shaped tracks 14. These tracks form almost a complete circle with the ends near the top side, however, spaced apart a short distance, as shown in Figures 3 and 4:, for a purpose later to be made clear. The outer edge of the wall 13 carries a laterally eX- tending flange 15.

The thresl er body 10 carries hinges 16 to which is connected a fan housing or cover 17, carrying on its outer face a bracket 18 forming journal for a shaft 19, which carries a pulley 20. This shaft 19 extends a substantial listance inside the housing 17 and, as shown in Figure 3, when the device is used for ordinary stacking, carries a conventional fan 21, said fan being removably mounted in any suitable manner. As shown in Figure 3, when it is not desired to bruise the straw, the tracks 14 have slid thereinto, and to be carried thereby, a suitable number of blank arcuated or segmentally shaped plates 22, a locking plate 23 being bolted to the wall 13 between the ends of the tracks securely to rc-v tain these plates in fixed positions relative to the saidtracks 14:. The cover will then be swung shut against the wall 13 and a flange 2 1 on the cover with the flange 15, serves to make an interlocking lap joint, as shown in Figure 2, to make a tight connection. A bolt 25 eX- tending from the wall 13 and through a seat 26 and a plate 2 7 is provided to clamp the cover tightly against said wall 13. The device new functions as an ordinary wind stacker.

Tfit is desired to bruise the straw before pneumatically stacking the same, the fan housing or cover 17 is hinged back and the plates 22 are slid out from the tracks 14.- after first taking out the anchoring plate 23. Then substitute plates 28, also arcuated or segmentally shaped, are substituted for the plates tit 22 in a similar manner, said plates 28 carrying bruising elements 29 in the form of spikes. These plates are then again locked in place by the anchor plate 23. The next step is to remove the fan from the shaft 19. Then a combination fan, bruiser, and distributor, element is mounted on the shaft in place of the fan 21. This element, shown best in Figures 2 and 4, comprises a. disk or plate 30 carrying on one face a number of fan blades 31 and on its other face, adjacent its periphery, an annular series of bruising spikes The same face of the plate under discussion also carries across its center and radially inwardly disposed with respect to the spikes 32, a diametrically arranged distributor paddle 33, and also on the same face radially disposed outwardly of the spikes 32, are provided auxi' liary fan elements 3 1. The spikes 32 cooperate with the bruiser elements 29 when the cover is closed and the paddle functions to distribute the straw from the chute in the direction of the spikes, to be bruised thereby. The fan elements 31 and 34 create a blast of air functioning to discharge the bruised straw from the housing 17 upwardly through the discharge pipe 35, as is usual in wind stackers.

The pipe 35 will be supported from the thresher body in the usual way and carries a handle 36, said pipe loosely fitting we a seat 37 so that the same may be easily displaced when it is desired to hinge the cover 17 outwardly. The outer side. of the cover carries frame elements 38, to which is connected a hanger 39 having its upper end, as at 40, pirotally connected to any appropriate frame element on the body 10 of the thresher. Thus, when the cover is swung outwardly, the same is properly supported.

From the above disclosure, the use and manner of o )eration of the improved straw bruiar has been made clear. It must also be appreciated that the change from a structure that will do ordinary wind stacking to a structure that will perform straw bruising can be accomplished easily and quickly.

Of course, the disclosure in the drawings has been selected by way of example only, and obviously changes can be made without departing from the spirit and scope of the invention as indicated in the following claims.
